About Boston

The historic urban core of the region, Boston’s waterfront covers Castle Island, Carson Beach, the Harbor Islands, and the Charles River locks. Locals and visitors engage in urban beachgoing, swimming in Dorchester Bay, walking the Harborwalk, and taking ferries to explore historic forts on the islands. Boaters and kayakers navigating the Harbor Islands must strictly adhere to the tide charts; the intricate channels between the islands are highly prone to shoaling, making a high tide necessary to safely dock and explore without running aground.
